Quick answer: World Mobile Token (WMTX) users should treat the current situation as an active security event. On September 20, Kraken paused WMTX deposits and withdrawals and later put trading pairs into cancel-only mode. KuCoin separately suspended WMTX deposits, while Bitvavo said it paused deposits and withdrawals as a precaution after a security exploit affecting the token.

What is happening with WMTX?

The strongest customer signal is not a single exchange outage: multiple independent venues restricted WMTX on the same day. Bitvavo explicitly described an active security incident and said its customer WMTX balances remained unaffected on the exchange while it assessed the situation.

Kraken's status page says WMTX deposits and withdrawals are paused until further notice and trading pairs were moved to cancel-only mode. KuCoin's official announcement says WMTX deposits were suspended for essential maintenance.

What should WMTX holders do now?

  • Do not deposit WMTX to an exchange showing funding as paused.
  • Do not repeatedly retry a withdrawal that the venue has disabled.
  • Preserve transaction hashes for any transfer already broadcast.
  • Check the token project's official security updates and your exchange status page before taking action.
  • Avoid swapping or bridging through unfamiliar services solely to bypass a pause.

What if a WMTX deposit is already pending?

Check whether the transaction has a valid on-chain hash. If it is confirmed on the source chain but not credited by the exchange, save the hash and wait for the receiving venue's guidance. A security freeze can prevent automatic crediting even when the blockchain transaction itself succeeded.

If no hash exists, the sending exchange may have stopped the withdrawal before broadcast.

What does cancel-only mode mean?

Kraken says users can cancel existing WMTX orders, but new orders cannot be placed and trades will not execute. This is more restrictive than a deposit-only pause and signals that users should verify the latest status before assuming normal market functionality.

Could scammers exploit the incident?

Yes. Security incidents often trigger fake “migration,” “reimbursement” and “wallet validation” campaigns. Never provide a recovery phrase or private key. Do not send WMTX to an address supplied by a stranger claiming to represent an exchange or project.
